today I want to fly an old mission with FPV Camera (sdk3.1 version) but it was not possible any longer.
I fly with a P3p (1.7)

I flow the mission more then 10 time with version 1.6 firmware without any problems.

Some mission info:
Total distance 5000m Max waypoint distance 1000m (always RC link)
17 waypoints
Distance between waypoints 50-300m
Altitude 80m
FPV camera


It looks that the SDK 3.1/firmware 1.7 restrict something by DJI.
I asked FPV Camera support team but there where no extra limitation in the DJI documentation SDK3.1

Is there anybody knows something more?

This morning I downgrade from 1.7 to 1.6 and the mission is working again.
So there are some waypoint/SDK limitation add in 1.7.

DJI can you help?

Problem solved!

I downgrade from 1.7>1.6 and.....install the 1.7 again and now it is solved.

I can fly the mission again!

I am glad you sorted it out
